PATTERN-CARD FOR LOOMS.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed- March 9, 1907. SerialNo. 361,613.

To all whom it may concern:

Be it known that I, JEAN GoHY, a subject of Belgium, residing at Ensival, near Verviers, Belgium, have invented new and useful Improvements in Pattern-Cards for Looms, of which the following is a specification.

The present invention has for its object to provide a construction of pattern card of particularly light weight for looms, and whereby any design whatever can be pro duced in weaving, without any dismantling and rearrangement of the card chain or the aid of any additional part, and this with but a very simple manipulation as will be hereinafter made clear.

The pattern card according to this invention is characterized essentially by the fact that it is provided with grooves, slots or the like made in the direction of the breadth thereof, and in each of such grooves or'the like is placed a sliding stop piece arranged in such a manner that it can slide therein and be fixed at one or the other end of its travel.

In the annexed drawing are shown by way Of example various forms of carrying out the invention.

Figure 1 represents separately certain of the parts which may enter into the construction of a card which is to be providedwith two rows of holes. Fig. 2 is a side view of one of the parts or plates shown by Fig. 1. Fig. 3 shows how the two parts or plates are joined to form one complete card or separate part of the card chain. Fig. 4 is an edge view of a complete card. Fig. 5 is a transverse section through the line A B of the two cards shown by Fig. 3. Fig. 6 shows a variation in which each part or separate card is provided with a single row of holes. Fig. 7 is a transverse section through the line A B of Fig. 6. Fig.8 shows another variation in which the slots, openings or the like are made directly in the plates formin the parts of the card. Fig. 9 is a transverse section of one of the parts of the card.

In the forms shown by Figs. 1 to 7 each card or element of the card chain is formed of two similar plates 1, each having a certain number of indentations or recesses 2 forming ways in which may be engaged small plates, shutters or slides 3. The plates 1 are held between. two plates or outside sheets 4; (Figs. 4, 5, 6 and 7) pierced with one or two rows of holes 5, or 5 and 6, of suitable shape to permit the entering into these holes of the selecting needles of the yoke levers with which the card chain works. The plates 1 are arranged between the sheets or covers 4 so that one row of holes 5 corresponds to the ways 2 made in one of the plates 1, while the other row of holes 6 (when two rows of holes are used) corresponds to the ways 20f the second plate 1. These two plates 1 are spaced apart to provide a certain space 7 (shown in dotted lines in Fig. 3) in which can be inserted a pin or needle 8 which may be manipulated from the outside of the card by a top piece or a button 9. Under those conditions, as may easily be seen, the small plates, shutters or slides 3 being inserted in the ways 2, such slides may be brought opposite the holes 5 forming the upper row in the plates 4, or opposite the holes 6 forming the lower row in these plates. It is sufficient for this to draw the needle 8 from its groove 7 and to then slide the shutters 3 in one or the other direction so as to make them pass into one or the other'o'f the ways 2. When any particular slides 3 are brought into the ways 2 corresponding to the upper row of the holes 5, the lower holes will be free and the selecting needles of the yoke levers will be able to enter into these orifices, but not those covered by the slides. Consequently it is very easy either to free all the holes 5 of the upper row, or all the holes 6 of the lower row, or alternatively, one hole of the lower row and one hole of the upper row, or again two successive holes of the upper row and two successive holes of the lower row, or to realize any other combination whatever corresponding to a certain design.

Fig. 3 shows as an example a combination which may be made, the blocked openings being shown shaded.

The displacement of the slides 3 in the grooves 2 forming the holders of the plates 1 may be very easily obtained by withdrawing the needle 8 and by the simple oscillation of the card or part of the card chain under consideration, the oscillation n one direction effecting to bring the slides 3 opposite one of the rows of holes 5 or 6, where a determined number of the slides may be held by a suitable iorward movement of the needle 8, and a fresh oscillationoi the card in the contrary direction effecting to bring back into the opposite indentations or ways 2 the slides not held by the needle. Thus for example by a first oscillation, in one direction, all the movable slides might be brought opposite the holes 5 of the upper row; the needle being then advanced to the extent of the two first holes 5, so as to hold in the corres onding indentations or ways the slides whic are there- 5 in, the card being thereupon oscillated in a contrary direction will bring all the free slides into the indentations or ways corresponding to the lower row of the holes 6. 'lhen again pushing forward the needle 8 to 10 the extent of two indentations or ways the corresponding slides 3 therein would be held and so on, so as to obtain alternately the blocking of two holes of the upper row and of two holes of the lower row (Fig. 3).

The different parts of the card chain are connected together by rings 10 or in any other suitable manner and each part may be provided at its ends with holes 11 in which may engage projections on the card cylinder.

As may be easily seen the above construction is not indispensable for carrying out the invention. The recesses or ways 2 might be formed directly in one of the plates 4 as will later be seen. The construction described lends itself however particularly well to obtaining at the same time lightness and rigidity as it permits the use of light material such as fiber for the plates 1, and steel plate for the plates 4.

The above construction, specially designed with a view to insure the positive control of the selecting needles may if necessary be modified by only using a single plate 1 held between two plates 4 bored with holes (Figs.

6 and 7). In this case the slides are movable and inserted by hand in the recesses or ways corresponding to the holes to be obtained. A needle 9, Fig. 6 inserted between the plates, keeps the slides in position.

F1gs.8 and 9 show a form of construction in which the ways 2 are made directly in the plates 4. Under these conditions, as may easily be seen, each card is reduced to a plate 4 provided with ways 2 arranged in the direction of the width of the card. The slides or shutters 3 are formed by washers or small plates 12 of any shape, but preferably round, provided with a central pin 13 passing through the plate 4 and projecting on the other side of this plate to receive a similar plate or washer 14 (Fig. 9) suitably riveted or otherwise fitted t0 the pin 13. The washers 12 and 14 thus form a kind of roller which is guided by the edges 15 of the ways 2.

The plate 4 is provided with a certain number of raised eyes 16 for the assage of the needle 8 intended to keep t e shutters in each of their extreme positions. The parts of the card chain are fitted .together as in the preceding case by means of the rings 10. The latter are preferably in one piece and may be placed in the grooves 17, into which they are introduced through the openings 66 18. Under these conditions the supporting tending through and crosswise of the card,

pin 8', when it is put in position, closes the openings 18 and thus prevents the pins 10 falling out.

The movement of the card chain made as shown by Figs. 8 and 9 may be effected as in 70 the previous cases by means of projections engaging in the openings 11 or better still by means of projections engaging directly in the space between two consecutive parts of the card chain. I

N 0 claim is herein made to the specific construction of the pattern card shown in Figs.

8 and 9 of the drawings, for the reason that said construction forms the subject matter of a divisional application filed by me on April 3, 1908, Serial No. 425,020.
